Re: How to provide a tapestry method to be access from another application?

[Eugen]

Hi,
is Your method exposed as event? Or You have a CORS exception? What is the
error on client side?

Re: Bootsrtap 4.x with Tapestry 5.4.x

[Eugen]

Hi,
I have integrated bs 4.1 with actual tapestry version.
Some components and core modules have to be overriden to work properly with
bs 4.1, also Glyphicons (if You are using it) should be imported manually.

Best regards
Eugen

Re: ServerSocket from within Tapestry

[Eugen]

Hi Christopher,
By decorating a Tapestry Service by @ServerEndPoint You can use all
Tapestry benefits like Injection etc.
You don't need to start any additional servers.. the application is already
deployed on Tomcat and Tomcat will serve classes decorated by
@ServerEndPoint. Important is to exclude the WS Pats from Tapestry's filter.
The code avove is usefull when You use the server standalone (without
Tomcat). Ffrom the Java-Websocket Docs: A WebSocket server by itself
doesn't do anything except establish socket connections though HTTP. After
that it's up to *your* subclass to add purpose.

kind regards
Eugen

Re: ServerSocket from within Tapestry

[Eugen]

Hi Christopher,
In my case the annotation @ServerEndpoint decorates an Service
implementation class.

I don't invoke any threads in WS Methods, but, i think You can use the
Tapestry's ParralelExecutor Service to optimize the processing of client
requests (see https://tapestry.apache.org/parallel-execution.html)

As WebSocket Client I use this library -
https://github.com/TooTallNate/Java-WebSocket

Re: ServerSocket from within Tapestry

[Eugen]

Hi Christopher,
to do somewhat similar I`m using Tomcat WebSockets (the Software are
deployed allways on Tomcat Server).
The Desktop application communicates over Java WS Client, WebPages over
JavaScript implementation. Transmitted Data is serialized into JSON Strings.
On Server-Side the @ServerEndpoint is a Tapestry Service what implements
specific WebSocket Functions (I'm using annotations, e.g. @OnMessage etc)

The ws Path should be added to IgnorePathFilter in AppModule:

public static void contributeIgnoredPathsFilter(Configuration
configuration) {
   configuration.add("/ws");
}

Eugen

List of embedded components

[Eugen]

Hello,
is there any way in Tapestry 5.4 to list all components embedded in a page
or component (defined in template file)?

The goal is to implement an annotation, @UpdateParentZone, that would
search for the first Zone in the parent components and add the found zone
to AjaxResponseRenderer to be updated after annotated function executed.

Thanks
Best regards
Eugen

Re: Simpler Hello World

[Eugen]

Hi,
if You don't like to use the template (.tml) files the entire job is to be
done in page class using the MarkupWriter,
a simple example:

public class Home{
void beginRender(MarkupWriter writer) {
writer.element("html");
writer.write("test");
writer.end();
}
}
this will write to the output html the text "test".
in this case, important is to start the page with the  element.

Best regards

Re: Tapestry-csrf-protection with Tapestry-Spring-Security.

[Eugen]

Yes, this is the "normal" way, another way is to make a tapestry form, f.e.:






and in OnSuccess event something like:

@inject
AuthenticationManager authenticationManager;

void onSuccess() {
Authentication authentication = new
UsernamePasswordAuthenticationToken(username, password);
Authentication authResult =
authenticationManager.authenticate(authentication);
SecurityContextHolder.getContext().setAuthentication(authResult);
}
this code throws an AuthenticationException if authentication fails.

@CommitAfter for GenericDao

[Eugen]

Hi,
I try to use the CommitAfter on a GenericDao, but the method does not
commit the transaction. Does it exists a worcaround to do that?

This is the code:

public interface GenericDao {
@CommitAfter
public void save(T entity);
}

public abstract class GenericDaoImpl {
@Override
public void save(T entity) {
entityManager.persist(entity);
}
}

public interface UserDao extends GenericDao {
}

public class UserDaoImpl extends GenericDaoImpl implements UserDao {
}

and respective advisor in AppModule:

@Match("*Dao")
public static void adviseTransactions(JpaTransactionAdvisor advisor,
MethodAdviceReceiver receiver) {
advisor.addTransactionCommitAdvice(receiver);
}

if I place the save() function into the UserDao all works fine.

Thanks in advice
Eugen

Re: componenent or mixin to trigger event when visible

Hi John,
in this mailing list it was a discussion about js events and zone

the message from Geoff Callender on 12.03 (he points to this example:

Re: [5.4] update zone with javascript

[Eugen]

Hi Matthias,
how do You define the myModule?
It should be a javascript file in META-INF/modules/myModule.js to be
automatically loaded as module.
alternatively You can contribute the ModuleManager in Yout AppModule
to laod desired JS file as module:
@Contribute(ModuleManager.class)
public static void loadExtraModules(MappedConfiguration configuration,
@Path("META-INF/assets/js/myModule.js") Resource myModule)
throws IOException {
configuration.add("myModule", new
JavaScriptModuleConfiguration(myModule));
}

Re: Excluding the last element in List during sorting

[Eugen]

Oh sorry, it was a wrong tip,...
You can provide an own GridDataSource, in getAvailableRows() return
your list size+1 (the empty row) and in getRowValue(index) return an
emty object for the index out of the list size.
The empty row will not be included in sort.

Re: [5.4] update zone with javascript

[Eugen]

Hi Matthias,
as second parameter of deferredZoneUpdate() function You need to
provide a event link to a function that returns a block or a
Zone.Body, something like:

@OnEvent("update-zone-event")
Object myEvent() {
   return request.isXHR()?zone.getBody():null;
}

the event Link, that should be passed to js Module can be created as follow:

public String getZoneUpdateLink() {
 componentResources.createEventLink("update-zone-event",
context).toAbsoluteURI();
}

JavaScript, something like
require([ "jquery", "t5/core/zone" ], function($, zoneManager) {
var moduleFunc, exports;
moduleFunc = function(myController, myZoneId, url){
$('#'+myControllerId).on("myEvent", function(e) {
zoneManager.deferredZoneUpdate(myZoneId, url);
}
};
return exports = {
moduleFunc: moduleFunc
};
});
}).call(this);

and initialization call in page/component:

javaScriptSupport.require("myModule").invoke("moduleFunc").with(myControllerId,
zone.getClientId(), getZoneUpdateLink());

'bootstrap/popover' Module

[Eugen]

Good day,
when I try to require the bootstrap/popover Module I become an error
in Firefox console:

[22:05:14.435] "RequireJS error: scripterror: Script error for:
bootstrap/popover
http://requirejs.org/docs/errors.html#scripterror, modules bootstrap/popover"

the tml file:
 Complete»

the java call failed:
void afterRender(){
javaScriptSupport.require("test").invoke("PopOver").with("complete");
}

this call works fine:
void afterRender(){
javaScriptSupport.require("test").invoke("ToolTip").with("complete");
}

the wrapper for ToolTip and PopoOver test.js module:
(function() {
define ("test", ["jquery", "t5/core/console", "require"] ,
function( $, console, require) {
var ToolTip, PopOver, exports;

ToolTip = function(elementId, params) {
require(["bootstrap/tooltip"], function(){
var element = $("#"+elementId);
if (!element) {
console.error("Element "+elementId+" not found");
return;
}
if (params)
element.tooltip(params);
else
element.tooltip();
});
};

PopOver = function(elementId, params) {
require(["bootstrap/popover"], function(){
var element = $("#"+elementId);
if (!element) {
console.error("Element "+elementId+" not found");
return;
}
if (params)
element.popover(params);
else
element.popover('show');
});
}

return exports = {
ToolTip : ToolTip,
PopOver: PopOver
};
});

}).call(this);

If the PopOver module is contributed manually in Appmodule all works
fine (the module name should be other name that popover!):
@Contribute(ModuleManager.class)
public static void setupBaseModules(MappedConfiguration configuration,
@Path("${" +
SymbolConstants.BOOTSTRAP_ROOT + "}/js/popover.js")
    Resource popover)
{
configuration.add("bootstrap/popovers", new

Is something wrong in my code or it is a Jira issue?

Re: Service Injection in @EntityListeners class

[Eugen]

Hi Thiago,
thanks for the quick reply
how to manage the instantiation of listener classes?
I'm contributing now the EntityManagerSource with custom
PersistenceUnitConfigurer (to avoid XML configuration) and tried to
add a ClassTransformer instance, but it is never called.

Service Injection in @EntityListeners class

[Eugen]

Hi,
it is possible to user service injections inside a @EntityListeners
annotated class?
I've tried to put the class in app.base, app.entites and app.service
packages, but the injected field is always null.

My code looks like:

public class EntityJpaListener {
@Inject
private SomeServiceservice;

@PrePersist
public void onPrePersist(Object entity) {
if (entity instanceof SomeEntity) {
System.err.println(service); // allways is null
}
}
}

@Entity
@EntityListeners(EntityJpaListener .class)
public class SomeEntity extends EntitySuperclass { // EntitySuperclass
is a @MappedSuperclass
...
}

Thanks
Eugen

ok, You need @Inject in services, in a page @PersistenceContext is enought..

Re: JPA

Hi, if You defined more persistence units in Your persistence.xml file
you should inject the EntityManager
 by
@Inject
@PersistenceContext(unitName = "unitname")

Re: many checklist's with one selected list

Hi Thiago,
thanks for Your help!!!
the checklists works fine now, each checklist has its own list of
enums and in processSubmission() of the parent component all list are
merged and copied back  to desired list.

Re: many checklist's with one selected list

[Eugen]

The mean of the grouping is only for display: each group becomes a
caption and is placed in a separate column, but the selected list to
persist should be unique
All would be nice if the checklist would append to the list and not empty it...

One option would be to to have separate lists for each group and to
merge they all in one list by form submition, but I would like to make
a component from the checklists and inject it in a form, in this case
the componet should be parametrized with more lists parameters that is
redundant...

what would be an alternative to do that?

the complete example:

public enum RiskType {
NONE, AGE, SEX, SMOKING, LIPID_METHABOLISM, GENETIC, ADIPOSIS,
GLUCOSE_INTOLERANCE, HYPERTROPHY, SCLEROSIS, HIGH_CREATININ,
ALBUMINURIA, CREATININCLEARANCE, HIGH_PULSWAVE, HIGH_ABI_INDEX,
DIABETES, CEREBROVASCULAR_DISEASE, CARDIAC_DISEASE, KIDNEY_DISEASE,
VASCULAR_DISEASE, RETINOPATHY}

public enum RiskGroup {
CARDIOVASCULAR_NO_RISK(new RiskType[] { RiskType.NONE }),
CARDIOVASCULAR_SIMPLE_RISK(new RiskType[] { RiskType.AGE,
RiskType.SEX, RiskType.SMOKING, RiskType.LIPID_METHABOLISM,
RiskType.GENETIC, RiskType.ADIPOSIS, RiskType.GLUCOSE_INTOLERANCE }),
CARDIOVASCULAR_TARGET_ORGAN(new RiskType[] { RiskType.HYPERTROPHY,
RiskType.SCLEROSIS, RiskType.HIGH_CREATININ ,RiskType.ALBUMINURIA
,RiskType.CREATININCLEARANCE, RiskType.HIGH_PULSWAVE,
RiskType.HIGH_ABI_INDEX}),
CARDIOVASCULAR_DIABETES(new RiskType[] { RiskType.DIABETES}),
CARDIOVASCULAR_ACC(new RiskType[]
{RiskType.CEREBROVASCULAR_DISEASE, RiskType.CARDIAC_DISEASE,
RiskType.KIDNEY_DISEASE, RiskType.VASCULAR_DISEASE,
RiskType.RETINOPATHY});

private final Listrisks;

RiskGroup(RiskType[] risks) {
this.risks = Arrays.asList(risks);
}
public RiskType[] getRisks() {
return this.risks.toArray(new RiskType[] {});
}
}

RiskSelect.tml


${message:no-risk-group-label}




${message:simple-risk-group-label}




${message:target-organ-group-label}




${message:diabetes-group-label}




${message:acc-group-label}



RiskSelect.java
@Property
@Parameter
Patientpatient;

@Inject
TypeCoercertypeCoercer;

@Inject
Messagesmessages;

@Environmental
private FormSupportformSupport;

public ValueEncoder getEncoder() {
return new EnumValueEncoder(typeCoercer, RiskType.class);
}

public SelectModel getRiskModel(String riskGroup) {
List optionModel = new ArrayList();
for (RiskType riskType : RiskGroup.valueOf(riskGroup).getRisks()) {
optionModel.add(new
OptionModelImpl(messages.get(riskType.name() + "-label"), riskType));
}
return new SelectModelImpl(null, optionModel);
}

And the page tml:

...




The next step would be render the checklists in a loop based on
groups, so any changes in the Enums would be displayed automatically

many checklist's with one selected list

[Eugen]

Hi,
it is possible to bind the same list of enums to many checklist
components inside one form?
My scenario is follow:
1 given are an enum:
enum A{ BA, BB, CA, CB, DA, DB}
2. the second enum split the enum A in more groups
private List enums;
enum Group(A[]) {
   B({BA, BB}},
   C({CA,CB}),
   D({DA,DB})};
3. Form:
 
 
 

Actually on form submit all selected values froun GroupB and C are
ignored and the listOfA contains only values from GroupD.

Thanks
Eugen

if the client should be redirected on an event (click) after timeout
happen, You can try to contribute the MasterDispatcher to do a refresh
(or a redirect) if session not exists. See

Re: Redirection afer ajax call when session timeout.

[Eugen]

Hi,
another option is to manage the Timeout in Javascript
on each render of the layout component Yout pass to a Javascript
function the maxInactiveInterval of the session and on Javascript side
starts an Timer with count down function. When the maxInactiveInterval
value is 0, a window.location.href = "/timeout"; is called.

Javascript module:
(function() {
define ([] , function() {
var exports, timeout, tick, init;
var remaining = 0;
var timer;

timeout = function() {
window.location.href = "/timeout";
};

tick = function() {
remaining = Number(remaining);

remaining = remaining - 1;
if (remaining <= 0) {
window.clearInterval(timer);
timeout();
};
};

init = function(timeoutInterval){
remaining = timeoutInterval;
timer = window.setInterval(tick, 1000);
 };

return exports = {
init : init
};

});
}).call(this);

Layout component:
@AfterRender
void afterRender() {
Session session = request.getSession(false);
if (session != null) {

javaScriptSupport.require("SessionInfo").invoke("init").with(session.getMaxInactiveInterval());
}
}

Re: How do I @Import a core css library?

[Eugen]

Hi,
the core css library are imported automatically, if You want to override
some styles, you should import it after importing of Autocomplete.css, it
could be made in CleanupRender phase:
@CleanupRender
@Import(stylesheet = {
"classpath:/META-INF/assets/MyAutocompleteOverrides.css" })
void cleanupRender() {
}

[Eugen]

Hi all,
a have a layout problem with an TextField decorated with Autocomplete mixin.
The .tml:
   
  
  State
  
  
  
 Country
  
  
 
The mixin is working fine, but follow layout is produced:
[image: Встроенное изображение 1]
How can this be fixed?

Thanks
